21.65 is what percent of 27.61 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 27.61 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 27.61, so we can write it down as 100%=27.61.
4. We know, that x% equals 21.65 of the output value, so we can write it down as x%=21.65.
5. Now we have two simple equations:
1) 100%=27.61
2) x%=21.65
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=27.61/21.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.65 is what percent of 27.61

100%/x%=27.61/21.65
(100/x)*x=(27.61/21.65)*x       - we multiply both sides of the equation by x
100=1.2752886836028*x       - we divide both sides of the equation by (1.2752886836028) to get x
100/1.2752886836028=x
78.413618254256=x
x=78.413618254256

now we have:
21.65 is 78.413618254256% of 27.61
